Remark:
Reference level for the relative attenuation arel of the TFS 167G is the maximum of the pass band attenuation amax. The maximum of the pass
band attenuation amax is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower
frequencies at the 3dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed at 167,0 MHz without tolerance.
The given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below even if the
centre frequency fc is shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production
tolerance for the centre frequency fc.

reference values only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
